英文摘要	Single wall carbon nanotubes (SWCNTs) were assembled onto tungsten tips by Van der Waals force. The influence of heat treatment and field desorption on these SWCNTs was studied by field emission microscopy (FEM) and field ion microscopy (FIM) respectively. The obtained FIM images are believed to result from a thin bundle consisting of three individual SWCNTs. FEM images from clean state of the same sample were in very good agreement with FIM images. After field desorption, field emission from SWCNTs follows the Fowler-Nordheim equation more strictly. The change in the slope of Fowler-Nordheim plots reveals that the heat treatment and field desorption result in changes of work function of SWCNTs. The change in both work function and FEM/FIM images show that a combination of heat treatment and field desorption is a feasible way to obtain clean carbon nanotubes with better field emission properties.; EI; 0; 1; 1-4; 23
